Abstract:

Fenugreek (Trigonella foenum-graecum L.) has a long and respected history of medicinal uses in Middle East and Persian medicine. The hypocholesterolaemic and hypoglycaemic effects of fenugreek were attributed to its major steroidal sapogenin, diosgenin and its major alkaloid, trigonelline. The knowledge of diosgenin and trigonelline biosynthesis is derived from studies of cholesterol and nicotinic acid production through acetyl-CoA→ mevalonate→ isopentenyl pyrophosphate→ squalene→ lanosterol→ cholesterol→ diosgenin and quinolinic acid→ nicotinamide adenine dinucleotide→ nicotinamide→ nicotinic acid→ trigonelline pathways, respectively. This paper reviews the secondary metabolites and metabolic pathways of diosgenin and trigonelline production in fenugreek as a medicinal plant and economical crop.

In vitro estrogenic activities of fenugreek Trigonella foenum graecum seeds.

BACKGROUND & OBJECTIVES Trigonella foenum graecum commonly known as fenugreek, has been widely cultivated in Asia, Africa and Mediterranean countries for the edible and medicinal values of its seeds. Earlier reports show that fenugreek seeds provide a mastogenic effect resulting in enhanced breast size. However, very little is known about its estrogenic effect. The present study investigated th...

Effect of Soaking and Germination on Nutrient and Antinutrient Contents of Fenugreek (trigonella Foenum Graecum L.)

Fenugreek seeds (raw, soaked and germinated) were analyzed for their chemical composition. Raw fenugreek seeds contained higher amount of dietary jiber 46.50% followed by 42.12% in soaked seeds and 32.50% in germinated seeds. Soaking reduced the level of total soluble sugars, reducing sugars, nonreducing sugars, dietary fiber and improved the protein and starch digestibility and availability of...

Influence of Different Seeding Dates on Fenugreek (Trigonella foenum-graecum L.) Forage Yield and Nutritive Value

Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value of three fenugreek cultivars as influen...

Effect of fenugreek (Trigonella foenum-graecum L.) intake on glycemia: a meta-analysis of clinical trials

BACKGROUND AND AIM Fenugreek is a herb that is widely used in cooking and as a traditional medicine for diabetes in Asia. It has been shown to acutely lower postprandial glucose levels, but the long-term effect on glycemia remains uncertain. We systematically reviewed clinical trials of the effect of fenugreek intake on markers of glucose homeostasis. METHODS PubMed, SCOPUS, the Cochrane Tria...

Fertigation effect of distillery effluent on agronomical practices of Trigonella foenum-graecum L. (Fenugreek).

The fertigation effect of distillery effluents concentrations such as 5%, 10%, 25%, 50%, 75% and 100% were studied on Trigonella foenu-graecu (Pusa early bunching) along with control (bore well water). On irrigation of soil with different effluents up to 90 days of harvesting, it was observed that there was a significant effect on moisture content (P < 0.001), EC, pH, Cl(-), total organic carbo...
